Hi,

I have created a COM addin for Excel 2003 using C#. I have an
automation addin class built into this addin that is displayed in the
Tools AddIns dialog. The automation addin contains some custom
methods like ISVALID(...)

The problem is that a separate XLA file loads with the addin and it
has the same method inside it (ISVALID(..)). In the Insert Function
dialog I have two different categories of functions "V11 Functions"
and "V12 Functions" but both have the same function names. Now when I
insert a function by typing its name in the cell (=ISVALID(B2)) it
picks it from "V11 Functions". I have to manually type
"=V12FunctionsProgID.ISVALID(B2)" to call in from "V12 Functions"
category.

Is there a way to rectify this problem by setting a preference on
which category will be used OR by inserting the functions with FULL
NAME (with ProgID)? If I insert using FULLNAME it works but changes to
short name automatically when I press enter. If again I press F2 in
cell and press enter it takes the V11 one.

Any help will be greatly appreciated

Thanks
Abhimanyu
